Description

本発明は、例えば車両に設けられているサンルーフ等の透光部を遮光シートにより遮光する車両用サンシェード装置に関するもので、特に手動式のサンシェード装置に関する。   The present invention relates to a vehicle sunshade device that shields a light-transmitting portion such as a sunroof provided in a vehicle with a light-shielding sheet, and more particularly to a manual sunshade device.

従来、手動式のサンシェード装置としては、特許文献1、2に記載されるようなサンシェード装置が知られている。   Conventionally, as a manual sunshade device, a sunshade device as described in Patent Documents 1 and 2 is known.

特許文献1、2に記載されるサンシェード装置では、サンルーフ下部の車両後方側に遮光シートを巻き取る巻取り装置を備える。遮光シートは巻取り装置に巻取られる方向に付勢されており、遮光するときは、手動で遮光シートを巻取り装置から巻取り力に抗して車両の前方に引出し、透光部の下側を覆う。   The sunshade devices described in Patent Literatures 1 and 2 include a winding device that winds a light shielding sheet on the vehicle rear side below the sunroof. The light-shielding sheet is urged in the winding direction of the winding device. When light is shielded, the light-shielding sheet is manually pulled out from the winding device to the front of the vehicle against the winding force and below the light-transmitting part. Cover the side.

遮光シートの前端には、車両の幅方向に延びる支持部材が取付けられ、更に支持部材の両端部には係止部材が取付けられている。係止部材は、車両ルーフに取付けられて、前後方向に延びる一対のガイドレールに摺動案内される構成となっている。   A support member extending in the width direction of the vehicle is attached to the front end of the light shielding sheet, and a locking member is attached to both ends of the support member. The locking member is attached to the vehicle roof and is slidably guided by a pair of guide rails extending in the front-rear direction.

係止部材は、ガイドレールとの間で所定の摩擦力が生じるように構成された機構を備え、巻取り力が加わる遮光シートを、乗員の希望する任意の位置に保持することができる。これによって、車室への採光量を調整することが可能となっている。   The locking member includes a mechanism configured to generate a predetermined frictional force with the guide rail, and can hold the light shielding sheet to which the winding force is applied at an arbitrary position desired by the occupant. This makes it possible to adjust the amount of light collected into the passenger compartment.

特許文献1のサンシェード装置では、係止部材に取付けたバネの荷重でガイドレール間に所定の摩擦力を得る構成である。また、特許文献2のサンシェード装置では、巻取り装置の巻取り力を利用して係止部材とガイドレール間の摩擦力を得る構成となっている。   In the sunshade device of Patent Document 1, a predetermined frictional force is obtained between the guide rails by the load of the spring attached to the locking member. Moreover, in the sunshade apparatus of patent document 2, it is the structure which obtains the frictional force between a locking member and a guide rail using the winding force of a winding apparatus.

EP1403109A2号公報EP1403109A2 publication WO2005/113292A1号公報WO2005 / 113292A1

しかしながら特許文献1のような構成のサンシェード装置では、長期使用により、バネ力の低下による摩擦力の不足、もしくは左右の係止部材とガイドレール間での摩擦力に大きな差が生じたりする。このために、希望する位置に遮光シートを保持できなくなるか、または遮光シートの開閉が操作し難くなるなどの問題が生じ易い。   However, in the sunshade device configured as in Patent Document 1, due to long-term use, there is a shortage of frictional force due to a decrease in spring force, or a large difference in frictional force between the left and right locking members and the guide rail occurs. For this reason, problems such as being unable to hold the light shielding sheet at a desired position or making it difficult to open and close the light shielding sheet are likely to occur.

一方、特許文献2のサンシェード装置の巻取り装置の巻取り力を利用して係止部材とガイドレールとの間に遮光シートの保持に十分な摩擦力を得る構成では、係止部材の形状、材質と巻取り力の微妙なバランス調整で達成する必要がある。このようなバランス調整状態を、長期の使用期間安定して維持し、所用の摩擦力を得ることは難しいという問題がある。   On the other hand, in the configuration that obtains a sufficient frictional force for holding the light shielding sheet between the locking member and the guide rail using the winding force of the winding device of the sunshade device of Patent Document 2, the shape of the locking member, It is necessary to achieve this by adjusting the balance between the material and the winding force. There is a problem that it is difficult to maintain such a balance adjustment state stably for a long period of use and obtain a desired frictional force.

本発明は、こうした実情に鑑みてなされたものであり、長期使用しても、確実に安定した停止摩擦力を維持するとともに、円滑な開閉操作が可能となる手動式のサンシェード装置を提供することを目的とするものである。   The present invention has been made in view of such circumstances, and provides a manual sunshade device that can maintain a stable stop friction force even after long-term use and can be smoothly opened and closed. It is intended.

上記課題を解決するため、請求項1に記載の発明は、車両に設けられた透光部を遮る全閉状態と該透光部を開放する開状態に移動自在な遮光シートと、前記車両に取付けられ前記遮光シートの移動方向に延在する一対のガイドレールと、前記遮光シートの前記全閉状態に向けた移動方向の端部に取付けられて一対の前記ガイドレール間を架橋する方向に延びる支持部材と、前記遮光シートを開状態へと移動させる作用力を及ぼす巻取り装置と、を備えるサンシェード装置であって、前記ガイドレールに当接する摺動部材と、前記摺動部材を押圧する作動部材と、該作動部材を介して前記摺動部材を押圧するための付勢力を作用させる弾性部材と、を備え、前記支持部材の両端部に取着されるとともに前記ガイドレールに摺動案内される一対の係止機構と、前記摺動部材の前記ガイドレールへの押圧および押圧解除をするための操作機構と、前記操作機構および各前記係止機構を連結する連結部材と、を備え、前記作動部材は、一端に作動側カム面を備え、前記摺動部材は、前記作動側カム面に当接する被作動側カム面を備え、前記作動側カム面と前記被作動側カム面とを介して前記弾性部材の付勢力が増幅され、前記摺動部材に伝達される構成としたことである。 In order to solve the above-described problem, an invention according to claim 1 is provided in a vehicle in which a light-shielding sheet that is movable in a fully closed state that blocks a light-transmitting portion provided in the vehicle and an open state that opens the light-transmitting portion, A pair of guide rails attached and extending in the movement direction of the light shielding sheet, and attached to an end portion of the light shielding sheet in the movement direction toward the fully closed state and extending in a direction to bridge between the pair of guide rails. A sunshade device comprising: a support member; and a winding device that exerts an action force that moves the light shielding sheet to an open state, wherein the slide member abuts on the guide rail, and an operation that presses the slide member And an elastic member for applying an urging force for pressing the sliding member via the operating member, and is attached to both ends of the support member and is slidably guided by the guide rail. A pair of Comprising a locking mechanism, an operating mechanism for the pressing and pressing release into the guide rails of the sliding member, and a connecting member connecting the operating mechanism and each said locking mechanism, the said actuating member, An operating cam surface is provided at one end, and the sliding member includes an actuated cam surface that contacts the operating cam surface, and the elastic member via the operating cam surface and the actuated cam surface. The urging force is amplified and transmitted to the sliding member .

また、請求項に記載の発明は、前記連結部材を前記操作機構から前記作動部材に張力を伝達する構成とした。 According to a second aspect of the present invention, the connecting member is configured to transmit tension from the operating mechanism to the operating member.

また、請求項に記載の発明は、1つの前記連結部材で各前記作動部材を連結するとともに、前記連結部材の中間位置で前記操作機構を係止させて連結する構成にした。 According to a third aspect of the present invention, the operating members are connected by one connecting member, and the operation mechanism is locked and connected at an intermediate position of the connecting member.

請求項1に記載の発明では、摺動部材が弾性部材の付勢力でガイドレールに押圧されることで、遮光シートを任意の位置に確実に保持することが可能となる。また、弾性部材の付勢力は、長期の使用期間での多少の劣化があったとしても、確実に安定した停止摩擦力を維持できるように大きく設定が可能となる。一方、操作機構を操作することで摺動部材はガイドレールに押圧されてない状態になるために、遮光シートは、常に軽い操作での円滑な移動が達成できる。また、摺動部材のガイドレールを押圧する力は、作動部材の作動側カム面と摺動部材の被作動側カム面を面形状の設定によって、弾性部材の付勢力を適切に増幅して容易に実現できる。 In the first aspect of the invention, the sliding member is pressed against the guide rail by the urging force of the elastic member, so that the light shielding sheet can be reliably held at an arbitrary position. In addition, the biasing force of the elastic member can be set to be large so that a stable stop friction force can be reliably maintained even if there is some deterioration during a long period of use. On the other hand, since the sliding member is not pressed by the guide rail by operating the operation mechanism, the light shielding sheet can always achieve a smooth movement with a light operation. Also, the force that presses the guide rail of the sliding member is easily obtained by appropriately amplifying the biasing force of the elastic member by setting the surface shape of the operating cam surface of the operating member and the operated cam surface of the sliding member. Can be realized.

請求項に記載の発明では、張力を伝達するケーブルなどによる連結部材にすることで、例えば鋼棒などによるリンク部材などで構成する場合に必要となる支持部品の必要がなく、安価に構成が可能となる。 In the invention according to claim 2 , by using a connecting member such as a cable for transmitting a tension, there is no need for a supporting part that is required when a link member such as a steel bar is used, and the structure is inexpensive. It becomes possible.

請求項に記載の発明では、1つの前記連結部材で各前記作動部材を連結する構成のために、部品数を少なく安価で、組付けも容易になる。 In the third aspect of the present invention, since the actuating members are connected by the one connecting member, the number of parts is small and the assembly is easy.

以下に本発明の実施形態を、図面を参照しつつ詳細に説明する。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

図1は、外光を車室1aへ導入できるようにするため、ルーフ10にガラスパネル11(透光部)を備えた車両1の外観を示す。尚、車両1における各方向は、図1中に矢印で示されている。   FIG. 1 shows the appearance of a vehicle 1 in which a roof 10 is provided with a glass panel 11 (translucent portion) so that external light can be introduced into the passenger compartment 1a. Each direction in the vehicle 1 is indicated by an arrow in FIG.

ガラスパネル11は、開閉機構を備えるサンルーフ装置(図示せず)によって開閉可能なものであっても、またはルーフ10に固定されて装着される天窓を構成するものであっても良い。ルーフ10の車室1a内側にはルーフ内装部材12が配置され、ルーフ内装部材12によって車両幅及び前後方向に矩形の窓部12aが開いて形成されている。   The glass panel 11 may be opened and closed by a sunroof device (not shown) having an opening / closing mechanism, or may constitute a skylight fixed to the roof 10 and attached. A roof interior member 12 is disposed inside the vehicle compartment 1a of the roof 10, and a rectangular window portion 12a is opened by the roof interior member 12 in the vehicle width and front-rear direction.

ルーフ10には、窓部12aを、遮光シート51によって開閉し、車室1aへの採光量を調整できるようにするサンシェード装置50が備えられる。遮光シート51は、窓部12aを遮る全閉状態と、窓部12aを開放する開状態に移動自在となっている。   The roof 10 is provided with a sunshade device 50 that opens and closes the window portion 12a with a light shielding sheet 51 so that the amount of light collected into the passenger compartment 1a can be adjusted. The light shielding sheet 51 is freely movable between a fully closed state that blocks the window 12a and an open state that opens the window 12a.

サンシェード装置50は、窓部12aの後方側に配置されて、遮光シート51を巻き取る巻取り装置55を有する。遮光シート51は布などの可撓性材料のシートで構成され、光の透過を遮断する。巻取り装置55は、遮光シート51に常に後方への引く力(開状態へと移動させる作用力)を及ぼす巻取り機構(図示せず)を備えた構成となっている。   The sunshade device 50 includes a winding device 55 that is disposed on the rear side of the window portion 12 a and winds up the light shielding sheet 51. The light shielding sheet 51 is composed of a sheet of flexible material such as cloth, and blocks light transmission. The winding device 55 is configured to include a winding mechanism (not shown) that always exerts a rearward pulling force (an action force that moves the light shielding sheet 51 to an open state) on the light shielding sheet 51.

更に、サンシェード装置50は、窓部12aの左右側に配置されて、ルーフ10に固定して取付けられた前後方向に延びる一対のガイドレール8を備える。   Further, the sunshade device 50 includes a pair of guide rails 8 that are disposed on the left and right sides of the window portion 12a and that are fixedly attached to the roof 10 and extend in the front-rear direction.

遮光シート51の前端部(全閉状態に向けた移動方向の端部)には、車両1の幅方向に延びて、一対のガイドレール8を架橋するように取付けられた支持部材52が取付けられる。   A support member 52 that extends in the width direction of the vehicle 1 and is attached to bridge the pair of guide rails 8 is attached to the front end portion (end portion in the moving direction toward the fully closed state) of the light shielding sheet 51. .

図2は、遮光シート51、ガイドレール8、及び支持部材52の部分を示す平面図である。尚、図2は、車両幅方向で右側のみを示すが、左側も右側と基本的に対称の構成となっている。   FIG. 2 is a plan view showing portions of the light shielding sheet 51, the guide rail 8, and the support member 52. 2 shows only the right side in the vehicle width direction, the left side is basically symmetrical with the right side.

図2に示されるように、支持部材52に形成されたシート連結部52aに遮光シート51の前端部が幅方向に亘って係止される。また、支持部材52の両端部には、一対の係止機構60が取付けられている。そして両側の係止機構60をガイドレール8に沿って摺動案内させることによって、支持部材52は、前後方向に移動させて、遮光シート51の開閉を可能にする構成となっている。   As shown in FIG. 2, the front end portion of the light shielding sheet 51 is locked to the sheet connecting portion 52 a formed on the support member 52 in the width direction. A pair of locking mechanisms 60 are attached to both ends of the support member 52. The support members 52 are moved in the front-rear direction by sliding the locking mechanisms 60 on both sides along the guide rails 8 so that the light shielding sheet 51 can be opened and closed.

また、支持部材52の車両幅方向の略中央部には、操作機構70がネジ78で取付けられている。操作機構70と各係止機構60とは連結部材4で連結される構成となっている。   An operation mechanism 70 is attached with a screw 78 at a substantially central portion of the support member 52 in the vehicle width direction. The operation mechanism 70 and each locking mechanism 60 are connected by the connecting member 4.

次に、図3、図4、及び図6を用いて、係止機構60の構成について詳細に述べる。図3は、操作機構70、係止機構60、及び連結部材4の構成を示す斜視図である。図4は、係止機構60の外観を示す斜視図である。また、図6は、図4におけるVI−VI部分での断面図であって、(a)は係止機構60が係止状態のときを、(b)は係止解除の状態のときを対比できるように示している。   Next, the configuration of the locking mechanism 60 will be described in detail with reference to FIGS. 3, 4, and 6. FIG. 3 is a perspective view illustrating configurations of the operation mechanism 70, the locking mechanism 60, and the connecting member 4. FIG. 4 is a perspective view showing the external appearance of the locking mechanism 60. 6 is a cross-sectional view taken along the line VI-VI in FIG. 4, where (a) compares the state when the locking mechanism 60 is in the locked state, and (b) compares the time when the locking mechanism is in the unlocked state. Shown as you can.

係止機構60はケース63を備えている。ケース63は、車両幅方向に延びるガイド穴63bを備えている。ガイド穴63bは、車両幅方向の中央側には壁部63a(図6)が形成され、車両幅方向の外側は開放されている。またケース63にはフック63cが形成され、係止機構60の支持部材52の中空部へ挿入後にフック63cは支持部材52に形成された係止穴52b(図4)に係合し、係止機構60は支持部材52に固定されている。   The locking mechanism 60 includes a case 63. The case 63 includes a guide hole 63b extending in the vehicle width direction. In the guide hole 63b, a wall 63a (FIG. 6) is formed on the center side in the vehicle width direction, and the outer side in the vehicle width direction is open. Further, the case 63 is formed with a hook 63c, and after being inserted into the hollow portion of the support member 52 of the locking mechanism 60, the hook 63c is engaged with a locking hole 52b (FIG. 4) formed in the support member 52, and locked. The mechanism 60 is fixed to the support member 52.

図6に示されるように、ガイド穴63b内には、作動部材61がガイド穴63bの延び方向にのみ移動可能に組み込まれている。作動部材61と壁部63aの間には、圧縮バネ64(弾性部材)が配置され、作動部材61を車両幅方向の外側に押し出すよう付勢している。尚、図3に示されるように、作動部材61には車両幅方向の中央側に延びる一対のアーム部61bが形成されている。アーム部61bの鍵状になった先端部は、ケース63のガイド穴63b内面から外に貫通する穴(図示せず)と移動可能に係合し、作動部材61が姿勢を保ってガイド穴63b内を移動できるように作用する。   As shown in FIG. 6, the operating member 61 is incorporated in the guide hole 63b so as to be movable only in the extending direction of the guide hole 63b. A compression spring 64 (elastic member) is disposed between the actuating member 61 and the wall 63a, and urges the actuating member 61 to push it outward in the vehicle width direction. As shown in FIG. 3, the operating member 61 is formed with a pair of arm portions 61b extending toward the center in the vehicle width direction. The key-shaped tip of the arm portion 61b is movably engaged with a hole (not shown) penetrating from the inner surface of the guide hole 63b of the case 63, so that the operating member 61 maintains its posture and guide hole 63b. It works to move inside.

圧縮バネ64との当接側と反対となる作動部材61の端部分の上面には、作動側カム面61aが形成されている。作動側カム面61aは、車両幅方向の外側ほど、その上下方向の幅が減少する傾斜面となっている。   An actuating cam surface 61 a is formed on the upper surface of the end portion of the actuating member 61 that is opposite to the contact side with the compression spring 64. The operating cam surface 61a is an inclined surface whose width in the vertical direction decreases toward the outside in the vehicle width direction.

更に係止機構60は、摺動部材62を備えている。摺動部材62には、作動部材61の作動側カム面61aと当接する被作動側カム面62aが形成されている。   Furthermore, the locking mechanism 60 includes a sliding member 62. The sliding member 62 is formed with an actuated cam surface 62 a that contacts the actuating cam surface 61 a of the actuating member 61.

図4に示されるように、ケース63には摺動部材62を車両の前後方向で挟むように配置された一対の縦壁部63d(図4には前側のみを示すが、後側も前側と同様の形状)が形成されている。また、図6(a)に示されるように、摺動部材62は、ガイドレール8が備える外側縦壁8bと内側縦壁8cによって車両幅方向に挟まれている。そして摺動部材62は、縦壁部63d、および外側縦壁8bと内側縦壁8cとでガイドされて、上下方向のみの移動が許容される構成となっている。
被作動側カム面62aと作動側カム面61aは、相互に当接することで、作動部材61に作用する圧縮バネ64の付勢力を、摺動部材62に増幅して伝達できる構成となっている。即ち、図6(b)に示される作動側カム面61aの角度αを45度以下に設定したとき、仮に両カム面間に摩擦がない理想的な場合であれば、作動部材61からの力は、大きい力に増幅されて摺動部材62に伝達される。そして、摺動部材62は、ガイドレール8の上内面8aに強く押圧される。
As shown in FIG. 4, the case 63 has a pair of vertical wall portions 63d disposed so as to sandwich the sliding member 62 in the front-rear direction of the vehicle (only the front side is shown in FIG. 4, but the rear side is also the front side. (Similar shape) is formed. 6A, the sliding member 62 is sandwiched between the outer vertical wall 8b and the inner vertical wall 8c included in the guide rail 8 in the vehicle width direction. The sliding member 62 is guided by the vertical wall portion 63d, the outer vertical wall 8b, and the inner vertical wall 8c, and is configured to allow movement only in the vertical direction.
The actuated cam surface 62a and the actuated cam surface 61a are in contact with each other, so that the biasing force of the compression spring 64 acting on the actuating member 61 can be amplified and transmitted to the sliding member 62. . That is, when the angle α of the operating cam surface 61a shown in FIG. 6B is set to 45 degrees or less, if there is no ideal friction between both cam surfaces, the force from the operating member 61 Is amplified to a large force and transmitted to the sliding member 62. Then, the sliding member 62 is strongly pressed against the upper inner surface 8 a of the guide rail 8.

実際の設計に際しては、両カム面間の摩擦を勘案した上で、角度αを適切に設定して、付勢力の小さい圧縮バネ64でも摺動部材62がガイドレール8の上内面8aに十分強く押圧されるようにしている。そして、摺動部材62がガイドレール8の上内面8aに押圧されているとき、係止機構60は、巻取り装置55の引っ張り力に抗して、ガイドレール8に対する支持部材52の位置を保持できる構成となっている。   In actual design, the friction α between the two cam surfaces is taken into consideration, the angle α is set appropriately, and the sliding member 62 is sufficiently strong against the upper inner surface 8a of the guide rail 8 even with the compression spring 64 having a small urging force. It is supposed to be pressed. When the sliding member 62 is pressed against the upper inner surface 8 a of the guide rail 8, the locking mechanism 60 holds the position of the support member 52 relative to the guide rail 8 against the pulling force of the winding device 55. It can be configured.

次に、図5に基づき、操作機構70の構成を詳細に説明する。図5は図3のV−V部分の断面図である。   Next, the configuration of the operation mechanism 70 will be described in detail based on FIG. FIG. 5 is a cross-sectional view taken along the line V-V in FIG.

操作機構70はハンドル部71を有し、ハンドル部71がネジ78で支持部材52の下側面に固定されている。ハンドル部71は中空部71aを備え、中空部71a内に押しボタン部材72を有する。ボタン部材72には車両前方に水平に延び、ハンドル部71を貫通して外側に突起するプッシュボタン72aが形成されている。また、ボタン部材72には、上方に延びるアーム部72bが形成されている。更に、ボタン部材72のプッシュボタン72aには、その延び方向にガイド穴72cが形成されて、ガイド穴72cにハンドル部71の中空部71a内に形成されたガイドロッド71bが挿入されている。ガイド穴72cとガイドロッド71bによって、ボタン部材72は車両前後方向(図5の左右方向)へ、図5に示される姿勢を保持しつつ移動自在に支持されている。   The operation mechanism 70 has a handle portion 71, and the handle portion 71 is fixed to the lower surface of the support member 52 with a screw 78. The handle portion 71 includes a hollow portion 71a, and has a push button member 72 in the hollow portion 71a. The button member 72 is formed with a push button 72a that extends horizontally forward of the vehicle and protrudes outward through the handle portion 71. The button member 72 is formed with an arm portion 72b extending upward. Further, the push button 72a of the button member 72 has a guide hole 72c formed in the extending direction thereof, and a guide rod 71b formed in the hollow portion 71a of the handle portion 71 is inserted into the guide hole 72c. The button member 72 is supported by the guide hole 72c and the guide rod 71b so as to be movable in the vehicle front-rear direction (left-right direction in FIG. 5) while maintaining the posture shown in FIG.

ハンドル部71の上側に位置した支持部材52の中空形状の内部に、回転部材75が取付けられる。回転部材75は上下方向に延びる回転軸75aを備える。回転軸75aの下側は、支持部材52に形成された軸穴に、また上側は支持部材52に取付けられた支持プレート部材77に形成された軸穴に支持されて、回転部材75は支持部材52に回転自在に支持されている。   A rotating member 75 is attached inside the hollow shape of the support member 52 positioned above the handle portion 71. The rotary member 75 includes a rotary shaft 75a extending in the vertical direction. The lower side of the rotation shaft 75a is supported by a shaft hole formed in the support member 52, and the upper side is supported by a shaft hole formed in a support plate member 77 attached to the support member 52. The rotation member 75 is supported by the support member 52. 52 is rotatably supported.

回転部材75は、回転軸75aから回転径方向の両側に延びて、上下に配置された一対の回転プレート部材75bを備えている。各回転プレート部材75bは、両側の端部で一対のピン部材75cで結合されている。また、1つのピン部材75cの位置に、回転プレート部材75bの下側に延びるように作動ピン75dが取付けられている。作動ピン75dは、支持部材52の下側面に形成された穴(図示せず)を貫通して、ハンドル部71の中空部71a内に延びる。作動ピン75dの下端部は、ボタン部材72のアーム部72aの上端部と当接する。   The rotating member 75 includes a pair of rotating plate members 75b that extend from the rotating shaft 75a to both sides in the rotating radial direction and are arranged vertically. Each rotating plate member 75b is coupled by a pair of pin members 75c at both ends. Further, an operating pin 75d is attached to the position of one pin member 75c so as to extend below the rotating plate member 75b. The operating pin 75 d extends through the hole (not shown) formed in the lower surface of the support member 52 and into the hollow portion 71 a of the handle portion 71. The lower end portion of the operating pin 75 d comes into contact with the upper end portion of the arm portion 72 a of the button member 72.

プッシュボタン72aを、図3及び図5に示す矢印Bの方向に押すことによって、アーム部72aは作動ピン75dを後方に押す。そして、回転部材75は図3に示される矢印A方向に回転する構成となっている。   By pushing the push button 72a in the direction of arrow B shown in FIGS. 3 and 5, the arm portion 72a pushes the operating pin 75d backward. The rotating member 75 is configured to rotate in the direction of arrow A shown in FIG.

次に、連結部材4について説明する。連結部材4は、一本の多少の弾性特性を備えた、例えば樹脂などの材料によるケーブルである。図3に示されるように、連結部材4は、回転部材75の一対のピン部材75cの間を縫うようにして通されている。即ち、回転部材75が矢印A方向に回転したとき、前方に出るピン部材75cに対しては外径の前側面で、また後方に後退するピン部材75cに対しては外径の後側面で、連結部材4が当接するように配索されている。更に、連結部材4は、両端で各係止機構60の作動部材61に連結される。   Next, the connecting member 4 will be described. The connecting member 4 is a cable made of a material such as a resin having a certain amount of elastic characteristics. As shown in FIG. 3, the connecting member 4 is passed so as to sew between a pair of pin members 75 c of the rotating member 75. That is, when the rotating member 75 rotates in the direction of arrow A, the pin member 75c that protrudes forward is the front side of the outer diameter, and the pin member 75c that moves backward is the rear side of the outer diameter. The connecting member 4 is routed so as to abut. Further, the connecting member 4 is connected to the operating member 61 of each locking mechanism 60 at both ends.

連結部材4は、操作機構70を操作していない取付け状態で、その弾性特性で圧縮バネ64の付勢力により適度に伸び、張力をもって延びている。このとき、連結部材4の長さを適切に設定することで、連結部材4に張力を与えつつ、作動部材61に作用する圧縮バネ64の付勢力の大部分を、作動部材61から摺動部材62に伝達するようにしている。   The connecting member 4 is moderately extended by the urging force of the compression spring 64 due to its elastic characteristics in an attached state where the operating mechanism 70 is not operated, and extends with tension. At this time, by appropriately setting the length of the connecting member 4, most of the urging force of the compression spring 64 acting on the operating member 61 is applied from the operating member 61 to the sliding member while applying tension to the connecting member 4. 62 is transmitted.

尚、上記で連結部材4を、例えば樹脂などの材料によるとしたが、圧縮バネ64の付勢力により、適切な張力をもって延びる特性を備えた金属ワイヤとバネの組み合わせなどの他の構成によるものであっても良い。   In the above description, the connecting member 4 is made of a material such as resin. However, the connecting member 4 is made of another structure such as a combination of a metal wire and a spring having a characteristic of extending with an appropriate tension by the biasing force of the compression spring 64. There may be.

操作機構70を操作していない取付け状態では、連結部材4の張力によって、回転部材75は図3の矢印Aの起点位置になっている。そして、回転部材75が矢印Aの起点位置のとき、プッシュボタン72aを、図5に二点鎖線で示す位置に保持される。このように、連結部材4に張力を利用してプッシュボタン72aに付勢力を与える構成となっている。
上記の操作機構70では、例えば操作感などの必要に応じ、別途バネなどを用いてプッシュボタン72aに付勢力を与える構成であっても良い。また、連結部材4を上記構成では1本にしたが、操作機構70と各係止機構60とを、夫々異なる2本で連結する構成にしてもよい。
When the operating mechanism 70 is not operated, the rotating member 75 is at the starting position of the arrow A in FIG. When the rotary member 75 is at the starting position of the arrow A, the push button 72a is held at the position indicated by the two-dot chain line in FIG. In this manner, the urging force is applied to the push button 72a using the tension of the connecting member 4.
The operation mechanism 70 may be configured to apply a biasing force to the push button 72a using a separate spring or the like, for example, as necessary for operation feeling. Further, although the number of connecting members 4 is one in the above configuration, the operation mechanism 70 and each locking mechanism 60 may be connected by two different members.

次に、上記のように構成されたサンシェード装置50の作動を説明する。   Next, the operation of the sunshade device 50 configured as described above will be described.

図1は、サンシェード装置50が完全に閉じた状態(全閉状態)、即ち遮光シート51で窓部12aを覆った状態を示している。このとき、支持部材52は、係止機構60の作用でガイドレール8の最も前側の位置に保持されている。   FIG. 1 shows a state in which the sunshade device 50 is completely closed (fully closed state), that is, a state in which the window portion 12 a is covered with the light shielding sheet 51. At this time, the support member 52 is held at the foremost position of the guide rail 8 by the action of the locking mechanism 60.

乗員がハンドル部71を摘まみ、そしてプッシュボタン72aを図5の矢印A方向に押すことで、操作機構70の回転部材75が回転する。回転部材75の回転によって、回転部材75にも連結される連結部材4の張力は、各係止機構60の作動部材61を車両1の中心方向に引寄せるように増加する。   When the passenger picks up the handle 71 and pushes the push button 72a in the direction of arrow A in FIG. 5, the rotating member 75 of the operating mechanism 70 rotates. By the rotation of the rotating member 75, the tension of the connecting member 4 that is also connected to the rotating member 75 increases so as to draw the operating member 61 of each locking mechanism 60 toward the center of the vehicle 1.

図6(b)に示すように、連結部材4が矢印C方向に引寄せられたとき、作動部材61は係止機構60が係止状態のときを示す図6(a)の位置から距離D移動する。この結果、摺動部材62のガイドレール8の上内面への押圧は解除される。   As shown in FIG. 6B, when the connecting member 4 is pulled in the direction of the arrow C, the actuating member 61 is a distance D from the position of FIG. 6A that shows when the locking mechanism 60 is in the locked state. Moving. As a result, the pressing of the sliding member 62 on the upper inner surface of the guide rail 8 is released.

摺動部材62とガイドレール8との間の摩擦が無くなり、乗員はハンドル部71を摘まみながら、支持部材52を車両後方の希望の場所へ手動で移動させることで遮光シート51を開状態として、車室1a内へ採光量の調整が可能になる。また、プッシュボタン72aから指を離すと、支持部材52は任意の場所で位置を保持するように係止される。   The friction between the sliding member 62 and the guide rail 8 is eliminated, and the occupant manually moves the support member 52 to a desired location behind the vehicle while holding the handle 71, thereby opening the light shielding sheet 51. The amount of light extraction can be adjusted into the passenger compartment 1a. Further, when the finger is released from the push button 72a, the support member 52 is locked so as to hold the position at an arbitrary place.

上記のように、構成され作動するサンシェード装置50では、摺動部材62が圧縮バネ64の付勢力でガイドレールに押圧されることで、遮光シートは任意の位置に確実に保持することが可能となる。   As described above, in the sunshade device 50 configured and operated, the light blocking sheet 62 can be reliably held at an arbitrary position by the sliding member 62 being pressed against the guide rail by the urging force of the compression spring 64. Become.

本実施形態によれば、互いに当接する摺動部材62の被作動側カム面62aと、作動部材61の作動側カム面61aの角度を適切に設定することで、作動部材61に作用する圧縮バネ64の付勢力を、摺動部材62に増幅して伝達できる。このために、摺動部材62を、ガイドレール8の上内面に強く押圧させることができる。強い押圧する力で、圧縮バネ64の付勢力が長期の使用期間で多少劣化しても、確実に安定した停止摩擦力を維持できる。換言すれば、付勢力を小さくした、小型の圧縮バネ64の利用も可能となり、製造コストの低減にも寄与できる。   According to the present embodiment, the compression spring that acts on the operating member 61 by appropriately setting the angles of the operated cam surface 62a of the sliding member 62 that contacts each other and the operating cam surface 61a of the operating member 61. 64 biasing forces can be amplified and transmitted to the sliding member 62. For this reason, the sliding member 62 can be strongly pressed against the upper inner surface of the guide rail 8. Even if the urging force of the compression spring 64 deteriorates somewhat during a long period of use due to a strong pressing force, a stable stop frictional force can be reliably maintained. In other words, it is possible to use a small compression spring 64 with a small urging force, which can contribute to a reduction in manufacturing cost.

また、摺動部材62のガイドレール8への押圧する荷重は、被作動側カム面62aと、作動側カム面61aの角度によって容易に設定できる。   Moreover, the load which the sliding member 62 presses to the guide rail 8 can be easily set by the angle of the operated cam surface 62a and the operating cam surface 61a.

更に、係止機構60の解除後は、摺動部材62がガイドレール8に押圧されてない状態になるために、遮光シートは、常に軽い操作での円滑な開閉が達成できる。   Furthermore, since the sliding member 62 is not pressed against the guide rail 8 after the locking mechanism 60 is released, the light shielding sheet can always be smoothly opened and closed with a light operation.

連結部材4は、張力を伝達するケーブルなので、例えば鋼棒などによるリンク部材などを用いて係止機構に押す力を伝達して解除作動させる構成とは異なり、リンク部材を支持する部品等の必要がなく、安価にできる。   Since the connecting member 4 is a cable that transmits tension, the connecting member 4 needs a component that supports the link member, unlike a configuration in which a pushing force is transmitted to the locking mechanism using a link member such as a steel bar. There is no, and it can be made cheap.

なお、本実施形態では、1つのサンシェード装置50の遮光シート51により窓部12aを遮る全閉状態と作っているが、例えば2つのサンシェード装置50を用いて2つの遮光シート51により全閉状態を作ってもよい。その際、2つのサンシェード装置50のガイドレール8を共用にするとよい。   In this embodiment, the window portion 12a is blocked by the light shielding sheet 51 of one sunshade device 50. However, for example, the two light shielding sheets 51 are used to form the fully closed state by using two sunshade devices 50. You can make it. At this time, the guide rails 8 of the two sunshade devices 50 may be shared.
